When I use the following command :

the migration works fine but in the destination host the migrated vm is paused and I can't unpause it and I need to reboot the vm to be able use it in the new host. When I try to unoause it Igot the following error message: 

<< Error unpausing domain: internal error: unable to execute QEMU command 'cont': Resetting the Virtual Machine is required >>

How can I solve this problem, or is there an other way to make a live migration with libvirt??

Thank you for you consideration.
